Glad you got it sorted and with a nice result, sorry I delayed you doing so by using the dyno all day yesterday.

Hi,
another quick up date for the subscribers to this thread, the latest billet wheel design fitted to a GT30, we may name it "GT30 Billet +".

Please note we had to run the car in 4th gear as it just lit up all four wheels in 3rd, this makes the spool appear around a 1000 RPM less.
Now off to santa pod tomorrow to see how it performs or if Mikee can break the gearbox casing again.
cheers

(And why wouldn't you, with the option of 451!
).But when you do, would you post up your subjective thoughts on the SC42 Billet's spool, when compared to your previous 18g? I'm interested.

Nice to have met you and Lee yesterday - you both got blinding results from the unbeatable SC billet/JGM combo.

(And I got what I 'wanted' too
).

Hi,
this is exactly why we brought out the SC42 billet, some people think that the SC46 Billet will be a bit laggy and overkill, laggy its not by a long way but overkill on a 2.0 ltr it may be on some set ups.
The 46 can tend to choke up a bit over 420 BHP on 2.0 ltr engines and I stress on some set ups only, whereas the SC42 Billet doesn't as it is designed for around 420 BHP and with its smaller exhaust wheel has a slight increase in spool.
The 42 Billet has shown its capability to produce over 450 BHP with a 20% meth mix and there was more to come, Simon (JGM) held it back to save the standard gear box.
Both the turbo's are stunning, its a case of BHP verses spool but either way there is not much in it, and as I stated earlier, on a 2.0 ltr with certain set ups the SC46 Billet wont go over 420 BHP so you may as well go with an SC42 billet and gain a little spool, but unless you try the 46 we would never know if on your set up it would have worked fine.
cheers

So could I try before I buy???
46 on first - if it chokes, then swap out for the 42! Win-win.
Just have to suffer the potential duplictated labour costs for the 42's fitment. (Unless SC waive them as a goodwill gesture...?

Glenn, you prob didn't bother with the above V-Power map on the drive home as you no doubt still had meth in the tank, and used the VP+meth map instead?

).Yeah i did drive home on the meth map but rain stopped play so no chance of me dropping the hammer,as soon as im back on the v-power map i`ll post up my findings for you no worries.
Oh yeah didn't think off the labour cost!!!
Couldn't afford it twice prob best to go for 42 to be on safe side then.. But I know lateral have also just released the billet range of the mdh and mdt so really torn which way to go now!!!!
the 18g glenn had was amazing but the sc42 is simply another level pal.great figures btw on your 20g.about what you thought pal.you should have said that you need some meth to break 400 and i could have give you some

(Not sure on their 'policy' on that....)

Annoyingly, my particular motor, for whatever reason, can only hold 1.4bar. If it could have held, say, 1.6, 390-400 would surely have been in the bag. I even fitted a 17.5-20psi (1.2-1.36bar) spring in my Forge T2 w/g act. - but to no avail.

That said, I'm happy now... And torque, is just below 350lb ft at 349.2 -- so on the right side of "5-sp. friendly". Probably. lol

On the Litchfield twin scroll thread I queried as to wether the LM series were true twin scroll or just twin entry, it transpired that they were mere twin entry! I'm surprised this hasn't been picked up on. The SC series are true twin scroll this immediately puts them ahead of the LMs.
However, what is your reasoning behind why one turbo is "ahead" of another.... just from the way the exhaust housing volutes are configured?
There is more to the way the turbo performs than the volute trust me.

I contacted full race before going for a LM/SC but there twinscroll turbo doesn't fit RHD cars

No doubt you'll know a lot about these to turbos to

I'm sure you will be mega impressed Immy! 
I know the potential benefit of twinscroll volutes, but I also know the specification of compressor and exhaust wheel also plays a massive part in how the turbo responds, spools and makes it ultimate power.
Like I said.... it's not just about the "snail".
The comparisons with my very own car and my various turbo testing highlights that nicely.... even with a "lowly" twin entry design.
It wouldn't be right for me to post data on this thread, so have a look at the latest comparison graph on my project thread I have just posted.
Look forward to your results Immy and as I have said, I'm sure you will be very very happy with your set-up.

would be nice to see the results of the fabulous sc42 and sc46 maxxed out when whe have changed our gearboxes.at 460 bhp it is positively rocket prepelled so once the gearbox is changed who knows how much its really capable of.although 460 bhp is not to be sniffed at
It's a better spec for less money.

iPhones for one, autocorrect Kev into keV as it's an abbreviation for Kiloelectron Volts, rather annoying if that's your name, like me 
And well done to Mikee for his new PB at the weekend using the new GT30 billet +, i'm sure keV
will provide an update soon
